Behind Laser Power and Energy Measurement Technologies

FOREWORD Laser Point manufactures a complete range of state-of-the-art detector heads and monitors for measurement of powers and energies of all lasers, from UV to the Far Infrared, in any application within the industrial, medical or scientific fields. Those detectors can mate to a whole family of precise and sophisticated monitors and meters which include intelligent detector connection, analog and digital displays, analog and digital outputs and application software . TECHNOLOGY Laser Point has put a lot of technology into the design of its heads. A head is substantially made of a sensor disk and a housing with its heat sink or cooling devices. Each of these assemblies are critical in view of the final performance of the system. Parameters like thermal stability, linearity, spatial uniformity, heat dissipation are calculated by our Engineers and extensive thermal SW modelling (Thermal Analysis System-TAS) is made to verify the behaviour and achieve the highest reliability even in those demanding environments represented by high power lasers . Absorbing coatings are another important chapter in the head design. They have to face high damage thresholds as a function of the wavelength of use. LaserPoint has adopted various types of radiation absorbers, simulated by TAS and deposited with the latest technologies (e.g. plasma) under the tightest specifications, to resist extreme thermal and mechanical stresses. SELECTING A MEASUREMENT SYSTEM The selection of a measurement set-up is, in general, an easy task. On the following pages you will find detailed specifications for each of Laser Point’s heads and readout units that will help you in defining what is needed for your application. Of course there may be exceptions or special requirements: in those cases feel free to apply to our Engineers or Distributors for complete technical support. The first step in the selection is to look for a detector capable to match the power and/or energy specifications of the laser; the next is to select a monitor that meets with user’s requirements, e.g. having a graphical display or an application SW. The entire working range has to be determined. The Power or Energy Resolution represent the minimum values which can be detected with an optimum signal-to-noise ratio, while the Max Continuous Power or the Max Energy are the maximum values at which the detector can safely work with no time limits. Nevertheless, should there be the necessity to make measurements at higher powers or energies, this can be done for a limited period of time, up to 1.5 times the max value (Intermittent Power Use). Verify if Absorber Type, Wavelength Range and Max Average Power/ Energy Density specs are consistent with the laser type; furthermore when working with short pulses (as is the case of various medical lasers or Q-switched Nd-Yags) and want to measure average power, attention has to be given to the Max. Peak Power Density. LaserPoint has a wide selection of products whose absorbers, like those working on the volume absorption principle, offer the highest damage resistance to short pulses. The Cooling type is another feature to look at; if bringing water to the head is a problem, there are convection or fan cooled detectors which can be used. For example, our A-600 head can work at 600W continuously or dissipate 800W for a short period, but that’s really a technological goal of LaserPoint thermal design. For higher powers water cooling is necessary. Finally, LaserPoint’s versatile and best-buy monitor PLUS or industry favorite LPM are the user friendly meters to be associated with any of LaserPoint detectors.


OPERATING PRINCIPLES OF THERMAL HEADS This section describes the very basics on which LaserPoint’s sensors and detectors work .It is intended to introduce the laser user with terminology and principles which are repeatedly mentioned in the catalog and can be used as a help in choosing the power/ energy instrumentation. Thermal methods of measuring power and energy are those in which radiant energy is absorbed and converted into heat, thus creating a temperature rise in the absorber. The absorbed energy can then be measured by monitoring a temperature gradient between the hot area ( where the laser strikes) and a cool area (where the generated heat is dissipated). This measurement can be done by means of thermocouples arrays (thermopile). The temperature difference will generate a voltage at the end of each single thermocouple, so if the array is duly distributed, the resulting total voltage will be proportional to the incident power or energy. As the generated voltage depends on the temperature difference between the hot and the cold areas it results that there is no influence of ambient temperature on the measurement. Thermal detectors exhibit an intrinsic high degree of linear response at the increase of power levels (linearity); a compensation for the minor drops in linearity occurring at the working temperature extremes are made with the use of thermistors. Linearity of LaserPoint’s detectors, thanks to their optimised thermal design, is excellent: as an example, for the W-1000 head as measured by PTB (Physikalisch-Technische Bundesanstalt) in the range between 60-1000W, it remains within +/-1 % without compensation. The generated heat all flows through the thermocouples, whether they deposited on circles (radial thermopiles) or linearly, with the hot and cold areas facing each other (axial thermopiles). Since the total signal is given by the sum of contributions from all thermocouples, the result is the independence from laser beam size and position The response time is determined the thermal resistances, the thermal capacities and, mostly, by the geometrical sizes of the sensor disks. The intrinsic response times of detectors is significantly reduced by appropriate acceleration algorithms in LaserPoint’s monitors. A detector like LaserPoint’s A-300, which has an intrinsic response time of 11 sec due to its very large area, displays the final power value only after 3.5 sec. To dissipate the generated heat a thermal sensor must be placed within a housing which, depending on the amount of heat to be driven away, can work by simple convection, have electrical low voltage fans or be water cooled. So as the thermal contact between sensor and housing is very critical since it might generate overheating of the sensor and instabilities in the signals, the final shape and dimensions of the heads must be carefully designed to maintain the sensor temperature within its working limits. An example of excellent thermal dimensioning is LaserPoint’s W-6000 head, which can safely work up to 9KW.


A NEW APPROACH ON THERMAL HEADS DESIGN: THE FIT AND FIT-H PRODUCT LINES In some sections within this catalog Fit detectors are mentioned. These heads are available for different applications : as laserprobes, where a full product line bears the same Fit name and as detector heads for the PLUS monitor, the Laser Process Monitor LPM and the PC-Link readout. Fit, acronym for Fast Integrative Thermopile, is a measurement technique of temperature dynamics throughout thermopile sensors developed by LaserPoint (Patented.) which led to a novel family of detectors. A dedicated algorithm converts sensors data into fast , repeatable and precise readings. Fit detectors have provided a series of breakthroughs in laser measurement: infact, while keeping the advantages of thermopile detector heads (e.g. their use at any wavelength or their fast response times) , Fits need no water cooling even when working at several kilowatts, while still allow repeated measurements. As a laserprobe, no other similar instrument on the market has ever been so repeatable and precise, before . Fit detectors can be used in all those cases where availability of cooling water is an issue or when space is limited but ,above all, where long term laser power measurements are not necessary while quick, occasional checks are enough. In these cases the Fit detectors, either associated with a Plus monitor, an LPM or working as a standalone laserprobe, provide performance comparable to power meter measurements, at a real fraction of their cost. RADIATION ABSORBERS In your selections of laser detectors always consider that absorbing coatings are one of the most important elements in a laser measuring device: they are the first element the beam meets. If the beam is too small, or the mode is a sharp gaussian ( this is the case of slab lasers, for example) or the beam includes dangerous hot spots , then the measurement head will be damaged. So, it’s not only the measurement which will be invalid, but it’s also money a cost because a damaged detector needs to be serviced or substituted. LaserPoint detectors can measure over the complete range of wavelengths interested by lasers, up to many kilowatts of power and hundreds of Joules of energy. It is thus evident that there is a necessity to use many kinds of different absorbers to accommodate so many situations. What defines the goodness of a laser coating is its behaviour when it is subject to high powers, to converging and focused beams or when it undergoes to pulsed lasers with narrow pulse durations. This goodness is represented in terms of maximum power density ( expressed in W/cm2) and maximum energy density capabilities (expressed in J/cm2); they represent the maximum amount of power or energy an absorber can withstand before it gets damaged, given certain beam dimensions ( e.g. when the beam is focusing). The immediate consequence, when the coating is damaged, is that measurements are no longer reliable. A common attitude in the market is to advertise always higher power/energy densities; albeit coating performances obviously increase with the adoption of new technologies, the explanation is within the footnotes of datasheets: the higher is the density value, the lower is the absolute value of power or energy used to derive that figure. Why so? And what happens when powers are high, for instance in the multi-kW range? A rough but easy to understand example may help to unveil the under-laying mechanism. Imagine a water sink with its drain hose and a tap. If the volume of water from tap is lower than the volume the hose can drain, the hose will remove all water very quickly. If the flow from tap increases to a point where the volume is higher than the volume the hose can drain, the sink will fill and water will pour . A similar mechanism can be applied to heat in laser sensors: you can translate the heat as previous water, the laser absorber as the sink and the combination of sensor body + its cooling system as the drain hose. Unless laser power/energy is low, absorber materials can drain quickly the generated heat but, if the applied laser power or energy gets so high to reach the system’s limit (absorber + sensor mass + cooling devices) to remove heat very fast, heat will then pile-up to a point where absorbers melt. Of course the above picture has been extremely simplified, because mechanisms of heat transfer are far more complex and dependent on a number of factors, related to materials, geometries and cooling efficiencies. Nevertheless this picture should give the idea of why it is so important to provide customers with correct and comfortable specifications for the absorbing coatings, in particular in those regions where their use is at the limit for materials (e.g. high powers, small beams). A-Surface Absorbers- Surface absorbers consist in materials deposited onto substrates that can easily transfer heat,like high conductivity metals. They are used for CW lasers or other sources that emit long pulses (with duration >300µsec). Radiation is almost entirely absorbed within a thin layer by materials like special mattes or refractory materials and then released as heat which flows through the thermopile. ■ BBF Coating: for low powers and general purpose applications LaserPoint utilizes a black matte derived from astronomical research. The power density capability is limited to 200W/cm2, but has the important advantages of a flat spectral response in the range 0.19-25µm and the bearing of a very high absorbptivity (> 96%) over the entire range. ■ HCB Coating : A general purpose hard coating , developed for more demanding applications is used by LaserPoint for mid power lasers. It can be used over a broad spectral band (0.25-11µm) and some sensors ( as the W-200) bear specially shaped surfaces that reach a 97% absorptivity by dumping the radiation with multiple bounces. This coating reaches 2500W/cm2 at full power with 300W CW operation. At pulsed operations it can withstand up to 300J with long

(msec) pulses. ■ HPB Coating : standard broadband absorbers can hardly withstand the disruptive situations generated by industrial lasers. The HPB is a high density and high thermal conductivity coating for those demanding lasers available on LaserPoint heads from 200W to 3KW The HPB absorbers can withstand 4KW/cm2 for CO2 in CW operations. ■ SHC coating: the SHC is a real high power coatings. Performances of SHC are stunning and definitely place it to be the best laser coating available on the market. Laser Point’s specification curves for the SHC are based on test campaigns made with our customers in disruptive conditions and show that the properties of SHC are steps ahead any other coating: it withstands more than 12KW/ cm2 in CW operation, with an applied power of 1KW of Yag laser, or 40J/cm2 with laser diodes peak powers of 3.2 KW @1 msec! Compared to other absorbers for high powers which can be used on limited spectral ranges, SHC has also a very high absorption ratio ( > 85%) over an extended working range ( 0,25µ to 25µ), making it suitable for safe applications in almost all laser domains.

■ Excimer Coatings: LaserPoint has developed a very hard absorber with flat response in the range 190-400µm, ideal for its use with industrial Excimer lasers. It has also a remarkable high absorptivity at 10.6µm, so it may as well be used for CO2 lasers. The ridged substrate surface induces multiple reflections that increase absorption to the highest available levels on the market. In the UV the coating can withstand >0.3J/ cm2, high repetition rate, nsec pulses at 248nm and has a peak power density capability >20KW/cm2. B-Volume Absorbers-When heads with surface absorbers are used to measure lasers which deliver short time pulses ( lower than microseconds), heat has no time to flow and to be removed within the duration of the pulse length. Radiation remains deposited within in a thin surface layer where it generates a sudden overheating of the absorbing material and where the excess of energy will often cause ablation.

Surface Absorber : Short Pulses (<500µsec )

SHC Coating on Focussed Beam. No damage

Standard Hard Coating on Focused Beam: damage is evident


In those cases the technology of volume absorption is used, where a gradual, exponential decrease of radiation intensity occurs as it penetrates into the material. Total absorptions are obtained over 0.5-2mm depths rather than few microns: the consequence is a better distribution of energy and a far lower local temperature increase. Various types of glasses and ceramics are used by LaserPoint to cover the UV-C range (190-250nm) , the UV-A (250-400nm) and the VIS-NIR (BB absorber from 400nm to 3µm).Those absorbers can withstand peak powers of 100GW/cm2 and energy densities up to 30J/cm2. C-CoatingDamages. The damage threshold is defined as the level at which readings will change more than 1%. When exceeding this value the absorber surfaces will visibly change colour and the head calibration has to be reconsidered if the damaged area is important compared to the overall. In some cases a complete substitution of the sensor may be necessary. Yet, as very often happens, there may be a bleach on the coating but no at all, or just negligible change in the readings: those colour changes are barely aesthetical and can be accepted without other interventions on the head. DETECTOR-TO-MONITOR INTELLIGENT INTERFACING Each detector head is a unique device and has its own specifications; for example, sensitivity or the voltage output per incident W or Joule of laser power or energy , is different from head to head. Its exact value is derived by calibration and calibration data have to be available to the readout unit to provide accurate readings. Other parameters, like response times, are also specific for a kind of head and the monitor must have those values to provide suitable speed-up of readings. These are examples of information that each readout unit must get, once a detector is linked. The question then arises on how to supply the monitors with additional, specific information, like those mentioned in the examples. All detectors manufactured by LaserPoint come with a DB-15 connector that houses an E2PROM where all relevant parameter of detectors are stored. It’s LaserPoint Intelligent Identification System (IIS) : the detector automatically identifies itself to the monitor and stored data are supplied. The monitor knows what to do, whether it is a 3W or a 6KW head. This technology has another advantage, with a relevant budget impact: all detector heads from LaserPoint can be easily interchanged with any of the monitors and one single readout can be used with all detectors in the lab. SELECTING A POWER OR ENERGY MEASUREMENT SOLUTION Measuring power or energy can be done in many different ways and to obtain either basic or complex information. In the majority of applications it is done by the commonly known power/energy meters, by laser probes or OEM sensors. In each case the finality may the same (e.g. knowing the laser power) but real, final needs may be very different, as well as their consequent economical aspects. A power/energy meter is made of a detector linked to a monitor via the IIS connector, that stores all relevant data concerning the head. The monitor can work as a stand alone unit displaying the power/energy values and other information and can be connected to computers or chart recorders. Power/energy meters are high end instruments whose performances may vary with the number of features or complexity of the overall setup. Prices will follow accordingly . They are measurement instruments, the which thing means that they have to undergo to classes of precision, must have tight values of repeatability, need to be periodically re-calibrated (at least once a year) to trace their performance. For powers exceeding 100W the heads need an internal cooling system which could be a fan extracting heat from dissipating fins or water running through channels carved into the head. This is because power/energy meters must work continuously for long periods of time facing the direct laser beams, even many KWs, without problems. Their reliability and capacity to work indefinitely at the maximum powers or energies makes them the ideal instrument for


Cooling

Light penetrates and is absorbed by a thick layer of gradually absorbing materials (1-2mm thick) . Heat is generated within a volume and safely flows through substrate tothermocouples and cooling system. Volume absorbers can measure very short pulsesand high energies much better than surface absorbers.

Volume Absorber : Short Pulses (<500 µsec)


applications like: -Measurement of laser or laser system stability -Alignment of laser cavity -Alignment of optical setups -Measurement of losses -Derive statistical information on laser/ system behavior -Measure the power/energy ratio between 2 optical paths Doing all this is only possible by the association of a properly cooled detector with a complex electronics which reads the row data and elaborates/displays the measurements. Once the measurement session is over, the equipment can be easily removed and used elsewhere, with another laser or system. This is not so with OEM detectors. OEM detectors use the same sensors of power/energy meters embedded in simplified housings; they respond to the need of laser manufactures (in the majority of cases) to have a continuous monitoring of their sources and are permanently fixed into the laser head or the laser machine. But we are now talking of monitoring and not fine measurements: the associated electronics is in general very simple and limited to convert the sensor output into a signal manageable by the laser control unit. The power/energy value is displayed, maybe after basic signal treatment (e.g. the speed-up of response time) but no significant elaboration is made. Measurements are accurate and repeatable but the display of information is used to preset the power/energy levels necessary for an application , verify that set levels remain as previously fixed and no problems occur on the machine. Laser Probes only read power. They make a measurement in a fixed time period and are used to make time-to-time controls at the source exit, at the working area or before/after an optical component to check its losses. Probes simply tell which is the power level at the time of measurement, like a photo camera provides the picture of a shot taken at a certain instant; on the contrary power/energy meters can be imagined as movie or video cameras that show a real time and continuous evolution. For the above reasons probes cannot be used for alignments, monitoring of stability or provide statistical information which all require a continuous use . They are low cost devices and, until the introduction of LaserPoint’s Cronos and FIT series with their patented measurement and acquisition techniques, the market was only offering poorly repeatable and poorly precise instruments. FIT and Cronos have been the real breakthrough in this kind of measurement with the reduction of reading time (lowered from 20 sec or more to 4sec and 8sec) , the possibility of making several measurements without cooling and the complete automatism of measurement which makes them independent from errors generated by wrong timings. All these innovations have now brought those probes to have performances comparable to power meters (e.g. the FIT instruments have the same capacity of a power meter to repeat measurements with a ±1% error bar).


LP-EXPLORER: the Detector Finding Program

ON THE WEB OR ON THE CD ROM WITH YOUR CATALOGUE Our new EXPLORER program will let you find, in the easiest way, the proper heads that meet your measurement needs. Just by entering the laser parameters EXPLORER will calculate the power or energy densities specific for that beam. It will finally relate these values, together with the other laser data and available detectors, to define and display which heads, monitors and coatings can be used. EXPLORER can be either downloaded from the web or from the CD-ROM with your catalog. From the Catalog CD: go to Start>Run>X:\LP-Explorer\setup.exe (where X stays for the CD-rom drive number).Click OK and follow the instructions. After installation is completed, you may run the Explorer application from your desktop.

Using the Explorer program is then all easy. ■ Select

There are a few initial steps to be performed before entering the beam parameters: 1) -specify the laser type: CW or Pulsed. 2) -indicate the beam shape. Heads are chosen considering their sensitive diameter always to be at least 16% larger than the beam itself; infact, most of times beam sizes are specified at 1/e2, leaving a lot of energy-which must be taken into account- available outside the nominal size. 3)If “Pulsed” has been selected, the type of measurement to be performed has to be chosen, then: in “Only Power” the program will find heads and monitors which will measure only the average power. Vice versa, by selecting “Power & Single Pulse Energy” the program will decide which heads & monitors are available to measure both the energy of a single pulse and average power; for a correct measurement of avg power the repetition rate has to be > 3 Hz. 4)The last selection to be done is the kind of desired product: if the application involves long term measurements, laser alignments, the necessity of making statistics on measured values, etc then chose “Power & Energy Meter”. If the application is only a periodic check of laser power, then a “ LaserProbe” is probably what better fits your needs.


■ Input Beam Parameters, Explore and Reset Data keys In this frame you’ll need to enter your beam data with the appropriate measurement units. For a CW laser you will only need to insert Beam Diameter, Wavelength and Max Power. For a Pulsed laser it is necessary to add Pulse Width, Repetition Rate and Max Energy. Once all boxes have been filled , just click on the Explore key to obtain all information . If another type of measurement has to be done, e.g. at another wavelength, you can refresh the screen by clicking on the Reset Data key

LP Explorer Results Panel ■ Derived Beam Parameters This frame shows several important calculated beam parameters derived from your input data and will give a synthetic, yet exhaustive, picture of your beam . ■ Available Heads& Coatings, Damage Threshold at: All detectors that fit with specifications for your beam parameters are shown and, to simplify selection, head types are separately listed in their various versions of coatings or absorbers. Aside the head model is reported the corresponding level of risk of damage for that coating/ absorber when subject to the inserted laser parameters. This value is expressed as a % of the damage threshold. It will undoubtedly result that some detectors may be closer to the damage threshold than others : always prefer a head which is below the 50% of damage threshold. This will put the coating on the safe side from hot spots and compensate from laser modes.


To proceed on your selection you may single click on each head model to open the “Power/Energy Resolution with Monitor “ frame; a double click will open a pdf file showing both specifications and a mechanical outlook for each head of interest. Some additional selection criteria are more personal and depend on the way the head will be used or the kind of application; for example LaserPoint manufactures a series of compact heads designed to work intermittently or for short periods. They are the heads with double code (e.g. the A-40/200 series) which can extend their measurement range, repeatedly but intermittently, These heads have a temperature sensor and , when associated with PLUS/ LPM monitors , can be used until a COOL message is displayed . ■ Power/Energy Resolution with Monitor This frame displays another important information which has to be taken into account when selecting a detector: the power or energy resolution provided by a complete measurement setup. Resolution depends on the noise of both monitor and head and can be seen as the least value which can be read having a practical meaning. Whenever a monitor is then available for the selected detectors ( if not, a n.a.. is displayed), the box underneath each monitor model reports the achievable resolution. Always consider what the frame reports, both for determining which monitor has to be used, but mostly to be aware of the real minimum values ( at least 10 times the resolution) of Power/ Energy which can be read. ■ Coating and Absorber Curves Characteristics The program also lists the absorption and damage threshold curves for coating and absorbers used by LaserPoint . Once you have selected a head with its coating or absorber, you may click on the side key to visualize , as pdf files, the complete performance of the coating/ absorber itself. This additional check can be very useful if the head is intended to be used at other wavelengths or with different pulse lengths. ■ Print To print a hard copy of the screen, just click on the Print Key ■ Updates The latest version of the LP-Explorer is available any time from the LaserPoint website at http://www.laserpoint.eu


Calibrations at Laser Point NIST AND PTB TRACEABILITY Sensitivity , or the voltage signal delivered by a detector as a function of striking laser power or energy, is different form detector to detector for different reasons one of which is the spectral response of absorbing coatings: the percentage of absorbed radiation is never 100% at any wavelength, but is a lower value which changes with the wavelength itself . Sensitivity undoubtedly depends also on manufacturing variables but it also happens that power and energy meters change their properties with time, as environmental factors – usage in particular-, degrade or damage parts critical for an optimum performance. In order to grant precise measurement accuracy, LaserPoint supplies each of his instruments calibrated before delivery to the highest level of accuracy, with traceability to the National Institute of Standards and Technology (NIST) Laboratories in Boulder, Colorado (USA) and the Physicalisch-Technische Bundesanstalt (PTB) in Berlin (Germany). All LaserPoint detectors are subject to this Nist and PTB traceable calibrations and a Certificate, reporting the list of NIST/ PTB standards and instruments used in the calibration procedure, is supplied to prove it. To ensure that accuracy and performances of laser power and energy meters remain intact over the time, a regular schedule of calibration and preventive maintenance is needed. An industry standard is to recalibrate once a year: units can be shipped back at LaserPoint where, at a modest fee, a general check-up and recalibration of the detector will be done . CALIBRATION CAPABILITIES IN LASERPOINT LaserPoint owns a number of laser sources which are used for in-house calibration ; these sources cover powers up to 300W and include pulsed lasers. LaserPoint furthermore relies on contracts for the use of multikilowatt lasers and other sources with nearby Scientific Institutes for tests and calibrations at high powers. A number of detector heads, calibrated by the wavelength at NIST and PTB, are used as Standards for calibration procedures. To trace linearity even at high power levels , heads have been calibrated over their entire working range up to > 1KW for CO2 and 300W for Yag. All measurements, made by PTB and NIST, show high linearity of LaserPoint detectors and that their behaviour is well within standard specifications (3%). On the wavelength range 250-1100nm LasePoint can optionally supply calibrations at any wavelength based on NIST traceable spectroradiometer measurements.

Laser Power and Energy Heads HOW TO READ PRODUCTS ID CODE AND SELECT A DETECTOR HEAD To ease and speed up your selection we have assembled codes that synthetically describe the detectors; we just ask you to complete these codes adding the type of measurement and the wavelength of calibration . The complete code , to be used when asking for quotes or when ordering, is then straightforward and gives an accurate, synthetic and a no-doubt description of the heads and the way it is going to be used , which helps LaserPoint to serve you better and faster . Head codes , as you will find on the catalogue or given by the LP Explorer, report a string which synthesizes the head basic features : 1-Firstly we identify the cooling type. A stays for air cooling (which can either be by convection or forced: please check on the single head specs ); W stays for water cooling. 2-Then we identify the full scale power (e.g. 200 means that the head can withstand up to 200W). Some of the new heads have a double code separated by a / . (egg 40/200) : those are heads with sensors capable to withstand many times the max nominal power, in case of short term use. In these cases the first digits identify the maximum power on continuous operation; the latter digits report the max power when the head is used for a limited period . 3-The sensitive Diameter (D XX) is also displayed .Some detectors may have the same power but different acceptance areas as they have been developed for different applications. Chose which fits better for your case remembering that nominal beam diameters are always given to include the 86% (1/e2) of the beam energy. Real beams are larger ! 4- The last digits show which coatings or absorbers types available for each type of head. Sometimes more than one coating is available for that head. Select the model with the most suitable coating for your application: egg – HCB. For any doubt refer to coating specifications or take advantage of the LP Explorer . The following are the additional information we ask you to add: 5- Measurement Mode : detectors can be configured to work as Power Meters (P), as energy meters (E) or both (P+E). When constructing the code, specify which are the measurement modes of your necessity : e.g. -E 6-Calibration Wavelength :select from the tables in the Ordering Information the kind of available calibration wavelengths and add it to the code: e.g. -VIS Example of a Complete Code: A-40/200-D40-HPB-P-Y

Optional Accessories HIGH GAIN MODULES FOR LOW POWER MEASURES Module Mod. AD20, when plugged to the smart connectors of Laser Point’s low power heads up to 40W, increase the head sensitivity 10X and thus extend the measurement range toward lower powers by a factor of 10. For example, when connected to a 200 mW head (LaserPoint’s A-02-D12-BBF) the module will bring its full scale to 20 mW, allowing readings with 10 µW resolution. The overall measurement extension for that head will thus be 200mW to 10 µW, making of it a convenient alternative to photodiodes detectors, in many applications. Another module, Mod AD2000, is available, in this case only for the A-02-D12-BBF and A-02-D12-HCB heads, to bring the head full scale to 2W. The overall measurement range for this head will be 100µW to 2W. These modules are available for PLUS and LPM electronics

Applications of Power and Energy Heads ■ Measurement of long term stability Long term verification of stability, necessary for example for the final validation of a laser source, is made by directly placing a power meter head, e.g. associated to the PLUS monitor, in front of the laser. The main screen of PLUSSOFT shows the long term behaviour of up to 12 hours. Plus and PlusSoft also have the possibility to set hi and low alarm thresholds.

■ Alignment of laser cavities Alignments require continuous tweaking of cavity mirrors: during these actions values change very quickly and understanding whether tuning is improving or not need a proper tool. Digital displays, with their fast running numbers are very un-easy; on the contrary, analog displays with their moving needle require a lot of attention to catch the value. Bargraphs are of great help to provide an immediate feeling of the direction of alignment, like in LaserPoint‘s PLUS, to have a fast perception of tuning direction at the same time maintaining the possibility to read the reached value.

■ Alignment of optical set-ups Optical losses can be introduced by a number of reasons, like the non correct angular positioning of elements or by damaged components; more often a sensitive decrease of throughput can be reached by misalignments or simply by summing individual losses of optical components. A power/energy meter positioned along the beam path, permitting correct alignments and verification of losses, optimises yield and efficiency of the optical system.

■ Measurement of losses Verification of reflectivity, transmission and losses of beam splitters, filters and other optical elements can be done by inserting a power/energy meter in front or behind the component. Dynamic changes, like modification of behaviour or performances under the action of temperature variations, can be also monitored.

■ Statistical measurements of laser or laser machine behaviour Statistical measurements are used for monitoring quality aspects of a source, a laser machine or set-up. Having for references heads bearing a NIST (National Institute for Standard and Technology) and PTB (Physikalisch-Technische Bundesanstalt) traceable calibration, data can be used for internal files, for quality reports, can be added to manuals or given to customers. All relevant statistical information as Current Value, Min &Max Values, Average, RMS Stability, Standard Deviation are supplied by the PLUSoft on measurement periods as long as required. For easier handling, all statistical data can be transferred and saved on files or printed

Laser


Displays and Software SELECTING A METER FOR THE APPLICATION The first step in defining a measurement system is to choose the detector needed for a specific application with the help of the LP- Explorer program. The following step is the meter selection, based on the following three basic considerations: a)-where the meter is going to be used. For example, if the operator is a laser engineer who spends most of his time in the lab, then he needs multi-function and sophisticated equipment for his qualitative measurements and laser set-up alignment. Laser Point’s 4π is the small, battery operated meter designed for those applications. b)-which are the needed additional features. A different case is when budget or environment constraints require a simpler monitoring system. For these applications the tool can be the PLUS Monitor. For example if the requirement is the use of a power meter for the final validation of a laser system before its delivery to the customer, it may still be then necessary to do advanced statistical analysis .Laser Point’s PLUS-SOFT powerful analysis software extend measurement capabilities c)-foresee future developments. Perhaps in a near future there will be a service engineer who will need compact and low weight equipment when travelling. At the same time he will have the necessity to use different heads, e.g. for high and low powers. The PC-Link offers this possibility, since it mates with all LaserPoint detectors and can be plugged to any portable PC. The following at-a-glance table will help in a first selection.

PLUS-USB: Low Cost Digital Display for Thermal Heads The PLUS-USB model is a meter for advanced power and energy measurement that mates to all LaserPoint detectors via a proprietary Intelligent Interface System (IIS)connection. It is sufficient to plug the head connector into the meter port to get a calibrated instrument, already configured for reliable and accurate measurements. One of the great advantages of the IIS connection is that every Laserpoint detector can be associated to a PLUS monitor if measurement requirements become different, for example once a new head is added to the lab equipment or to the system. The PLUS has been structured in its only apparent simple design to match a very broad range of applications to any customer budget. Its price and performance are infact absolutely outstanding , since it has been specifically imagined and designed to be the tool for laser measurement available to all kind of laser operators: in addition to standard laboratory applications, the PLUS is infact very popular among service engineers and within job shops for its simple way of use and its sturdiness. UMBEATABLE PRICE TO PERFORMANCE ■ Easy and immediate The instrument can be managed by means of three soft-touch keys : -ON/OFF (Zero). During a measurement session, the key will also Zero stored measurement values and display. -T/P. Gives access to the Tuning Function and the Power Measurement Function. -E. The E key provides access to the single shot Energy Measurement Function . -The mW/ mJ leds light to show that the low Power/Energy Measurement Functions are enabled. ■ Power, Energy, FIT Operational Modes

The PLUS can work on different operational modes. It can be used as a power meter, as an energy meter or as a power probe up to 6KW, when associated to LaserPoint’s FIT-H series of heads. The selection is automatically made by the monitor when it reads the detector’s E2PROM, as soon as the unit is switched on. ■ Temperature Compensation

Temperature compensation is made by the PLUS, driven by an incoming signal from a temperature sensor located within the detectors, to linearize the head response and advise, by means of a warning message on the display, when the head has overtaken its max allowable temperature. ■ External Interfacing The PLUS can dialog with external PCs, plotters, etc via its Analog Output (0-2 Volts) or USB digital interface, which are provided as standard with the instrument. ■ Tuning

Through this function, a high resolution laser tweaking can be done. The existing power level is then displayed, together with the bargraph, initially positioned at the center of display. The bargraph will then will sweep downward or upward depending on tuning effectiveness.

The smaller digits shown on the display represent the percent variations after the initial value of power. ■ More features LaserPoint’s IIS -Intelligent Interfacing System- stores, within a set of most popular laser ranges, up tp six wavelength correction factors based on spectral data measured on head’s coating or absorber. The PLUS display may show : ■ EXC : for the UV and Excimer laser range (250-350nm) ■ VIS: for the Visible range (400-700nm) ■ LD: for the Laser Diodes range (800-900nm) ■ Yag: for the Nd-Yag wavelength at 1064 nm ■ Erb: for the Erbium wavelength at 2943 nm ■ CO2: for the CO2 wavelength at 10600nm Morever, operators may use correction factors with a resolution up to 1nm, provided on request by LaserPoint, to make reliable measurements at any custom or additional wavelenghts by using the: ■ UCF: ( User’s own Re-Calibration Factor). The User Calibration Factor gives customers the possibility to modify the value of original calibration sensitivity from 0.1% up to 999.9% (or from 1/1000 up to 10 times). The UCF box can be selected when scrolling for the wavelenght selection. The UCF can also be used to: - re-establish a correct sensitivity, in case of light damages on coatings -introduce a multiplying factor to track the main beam in case of detection after partializing devices (e.g. filters, beamsplitters, mirrors) -modify the original sensitivity to have measurements aligned to other references The UCF is effective on each measurement mode of PLUS (Power, Energy, Fit) .


PLUS-SOFT: APPLICATION SOFTWARE The Plus-Soft is a powerful application software provided as standard with each PLUS- USB. As shown below, the PLUS-SOFT can plot evolution graphs of time behavior of laser power, display energy or FIT readings in the form of histograms, show the absolute values of power and energy, provide all relevant statistical information and allow the storage of data to files, as a text format usable for Excel or other programs. The PLUS-SOFT also allows the management of laser processes and laser tuning. ■ Display Functions ■ Head Model: shows the head model in use ■ Lambda: shows detector’s calibration wavelength ■ SN: shows the head serial number ■ Actual Time: shows present day and time ■ POWER (W/mW); ENERGY(mJ/J): shows measured power or energy values. ■ User Calibration Factor: this number will multiply the actual measured value by a selectable factor to reach a desired value. ■ Head Temperature (°C): shows the temperature on heads provided with temp. sensor ■ ZERO: accomplishes an automatic Zeroing ■ TUNING: Enables the Tuning Function ■ SAVE: Enables the automatic function to save measurements on a file ■ PRINT: prints the displayed window ■ QUIT: leaves the program ■ Power Measurement Scales ■ Graph Power Max/Min (W) sets the extention of Y axis on power plot. ■ Graph Time: sets the duration of Time axis (X) for the power plot;available time scales are 60(sec), 2(min), 5(min), 30(min), 1(hour), 12(hours). ■ Laser Process Management

An important feature offered by the PLUS Software is the possibility monitor the ongoing laser process and get an alarm feedback in case the acceptable range for power/energy levels have exceeded the pre-set limit. This feature extends the PLUS applicability to rigorous control and monitoring of industrial applications. ■Process Parameters Setting -MAX/Min Power Levels: set process limits which remain visible on the screen as red lines, defining the acceptable working range. -Alarms: the rectangular Led, when green, shows that measured value is within the acceptable range .

When red, it shows that measurement is no longer within the acceptable preset working range and that an intervention by the operator may be necessary.

■Statistical Functions A full set of Statistical functions is provided by the PLUS-Soft. The Duration of acquisition interval can be selected to be as long as 24 hours. Once data have been gathered, SAVE enables an automatic saving on file for data recording or

future data tracking . The Statistical Functions include: ■ Max/Min (W,J): the max/min power/energy values measured during the last acquisition interval ■Avg (W,J): the average values of power/energy measured during the last acquisition interval ■PTP (%): the Peak-to-Peak stability ■STD (W): the Standard Deviation on measured data ■ RMS (%): the RMS stability

PlusSof Display for FIT-H type of Detectors


■ Laser Tuning A fast and highly visible Tuning Bar is available for laser tweaking or alignments. It displays variations of measured power on a double colour bar (green and red). The Power Variation (%) box shows how much power was gained or lost from an initial reference level. To remind the operator what has been the highest reached value, the Power Max(W) box stores the value . Evolution of laser tuning can also be comfortably followed on the screen.

■ Warning Messages All times measurement heads undergo to power levels above their full scale, an OVERFLOW alarm is displayed. The same way, whenever the temperature of a detector head is above its safety working limit, a COOL alarm message is displayed

HIGH GAIN MODULES FOR LOW POWER MEASUREMENTS

Module Mod. AD20, when plugged to the smart connectors of Laser Point’s low power heads up to 40W, increase the head sensitivity 10X and thus extends by a factor of 10 the measurement range, toward lower powers . For example, when connected to LaserPoint’s A-02-D12-BBF (200 mW, full scale) the module will bring its full scale to 20 mW, allowing readings with 10 µW resolution. The overall measurement extension for that head will thus be from 200mW to 10 µW, making of it a convenient alternative to photodiodes detectors, in many applications. Another module, Mod AD2000, is available in this case only for the A-02-D12-BBF and A-02-D12-HCB heads, to bring the head full scale to 2W .The overall measurement range for this head will be 100µW to

2W.

PC-Link: Single and Dual Channel USB Interface YOUR LAPTOP OR PC CONVERTED INTO A SINGLE OR DUAL CHANNEL POWER / ENERGY METER LaserPoint introduces the PC-Link, a smart head to USB interface that converts any PC or laptop into a powerful instrument which measures, analyses and records power and energy from any of LaserPoint detector heads. PC-Links are supplied with LaserPoint’s user-friendly communication software

packages for single channel or dual channel operations. When 2 heads are connected to the PC via two hardware boxes, the PC-2-Link SW is accessible at once on the PC screen to have data or compare signals from both heads . To work with PC-Links is very easy: it is sufficient to install the software, connect the heads to the interface units and these latter to the USB ports of a PC. No other operation and external power source are needed. This sophisticated monitor is plug and play with all LaserPoint heads. The advanced features of PC-Link, together with the fact that it is very compact and has low weight, make this monitor an ideal partner for service applications, laboratory or OEM use offering the convenience, flexibility and value of computer-based operations. The PC-Link is infact the candidate for use in laser machines, in particular when associated to LaserPoint’s FIT-H (Fast Integrative Thermopile Heads) family of OEM

detectors, that work up to 6KW without the need of water cooling. ■ Rich and Versatile Laser Monitoring The use of PC-Link is straightforward. The unit will recognize the power/energy head as soon as it is plugged-in; furthermore, the PC-Link will use its anticipation circuitry to insure a fast response and will use the calibration data stored in the intelligent connector (IIS) of each head to provide the most accurate measurement . The software packages for Single Channel and Dual Channel operation supplied with the PC Link are extremely rich. One feature offers the possibility to access to the User’s Own Calibration Factor (UCF) and a there is also X10 gain to enhance measurement flexibility (eg low power measurements to 20µW resolution ). Both SW versions allow to measure, analyse with full statistical functions (Min., Max., mean, and standard deviation) and record power and energy from all LaserPoint heads without the need of a display. Data from each detector can be logged simultaneously to file. The PC-2-Link software package includes in addition Mathematical functions to compare signals from both channel, e.g. A/B or A-B. The same SW also includes a ZOOM function which permits to see the details, e.g. random events or small fluctuations, within both signal tracks. ■ Measurements Modes: Power, Energy and FIT The PC-Link will dialogue with any head from LaserPoint to supply Power, Energy or FIT-type accurate readings.

The Power mode permits measurements of laser powers with direct display of their actual values. The screen also shows the evolution of power over time allowing stability measurements as long as several hours (up to 12 h depending on the PC). The FIT mode provides values of laser power by an automatic measurement cycle of 4 seconds with LaserPoint’s Fit-H heads. This family of detectors is used for accurate, yet once in a while readings and whenever simple power checks instead of long term measurements are needed. In this configuration the operator only has to expose the head to the laser beam and, after the correct timing generated by the PC Link’s’internal firmware, the measurement is over. (There is no need to provide the time window to the laser shutter). The Energy mode allows the measurement of single shot energy. This function is available on request on most of thermal heads manufactured by LaserPoint.


On top of the screen a toolbar is displayed. Each icon activates a particular software function, and a brief explanation pops up by simply moving the mouse cursor on the icon.

Saves acquired power data in a .txt file. The operator is simply requested to d ecide sampling time and file name. Acquisition data are continuously saved until the icon is next clicked. When the icon background is green, acquired data are being saved in the specified file. Prints the current screen by a printer. Activates measurements of laser power and its display Activates measurement of laser energy and its display Activates measurements with FIT-H heads Activates the Tuning function and its display Zeroes the instrument to remove any residual offset. The Freeze function stops the data acquisition and the statistic calculations in progress. Quits the application. Sets the input gain to x1. Amplifies head signals by a factor of 10: consequently the new full scale will be 1/10 of head’s nominal full scale and measurement resolution will be increased 10 times.

Two cross-air cursors permit to select an area and expand it to the full window Signals from 2 heads can be compared : A/B; B/A; A-B; B-A ; A+B; A*B

■ Statistics This function is also available on both channels of PC-2 Link SW. In the statistics section a series of statistical data are calculated and displayed. This function is available for the Power, Energy and FIT mode. Each time the counting of elapsed time has reached the set value, the following statistical data are calculated: ■ Pmax(W): Shows the max power value measured during the last acquisition interval ■ Pmin(W): Shows the min power value measured during the last acquisition interval ■ Pavg(W): Shows the average value of power measured during the last acquisition interval

■ Saving Statistics Data on a File Whenever measured data need to be saved on a file, this can be simply done by clicking on the “SAVE” button in the

statistic section. The structure of saved file (*.txt), as shown in the picture, is: -headline, reporting the head model, the calibration wavelength, the head serial number, the date and the time of saving action. -twelve columns

reporting date, time, calculated values of statistical measurements, temperature of sensor, sampling interval duration, alarms (cool, overflow) and active gain value are updated at each acquisition. Data of each saved file can be imported into a spreadsheet (e.g.Excel). ■ Laser Tuning Laser Tuning is only allowed in Power Mode and is used to achieve a high resolution tweaking of your laser. On top of the tuning window a toolbar is displayed. Each icon activates a particular software function. An analogue needle shows the direction of tuning. In the middle of the tuning display a box shows the actual power, while the maximum value reached during the tuning procedure is kept in a second box at the upper right corner of the screen. ■ Warning Messages Each time the laser power or energy exceeds the head full scale the OVERFLOW alarm is displayed as shown in the picture. Should a measurement head reach its limit temperature (overheating of a head may be due to problems to the cooling circuit such as low water pressure, lack of fluid, obstructions, etc, or poor heat exchange in air cooled heads), the COOL message will be displayed on the main window and the data displayed in the graph are pinned to the last power value acquired before the alarm.

Industrial Monitoring In laser material processing one of the most important information to have is the knowledge of laser power available to the work piece. Another important information is to know the beam stability or if the beam displaced from its original point of alignment; a third is the beam diameter. This is because, even in simple processing systems or machines, significant differences between the power measured at the laser's exit and the power at the work piece will occur. Moreover, by having those information, the machine operator will get additional information about the laser power independently from what the display at the laser source reveals and for the following operations : ■ Monitor Long term stability ■ Make Preventive Maintenance ■ Verify Process Reproducibility ■ Make Optics Alignments The following products from LaserPoint have been designed to provide the above important information and bear the following advantages: ■ Simple instruments for all level of laser operators ■ Provide stable and reliable operation even in harsh industrial environment ■ Short Measurement Time QUICK REFERENCE TABLE

Laser Process Monitor: the LPM THE SYSTEM The LPM is a device that overlooks at the behaviour of laser processes by monitoring the constancy of applied power or energy levels; as soon as the pre-set limits of those parameters have been overtaken, alarms signals will be delivered. Since a drop of set laser parameters simply means that something is changing within the system (often not immediately perceived), the LPM is then an extremely useful tool for laser machine operators. Typical applications are based on monitoring below the focussing head because, together with no affection on productivity and stops in manufacturing, it adds the following advantages: • to know the true power or energy delivered to the workpiece, independently from overall absorptions, optics

losses, dirt, etc. • exploit the synergic effect generated by cross-checking information coming from the process area and the laser

controller. This valuable information brings the LPM to be used in a variety of applications: • to provide immediate warnings for predictive maintenance and eliminate downturns on the laser machine, • to improve laser machine and process reliability, • to speed-up alignments of beam delivery components, • to control the system stability over time • to control the constancy of process parameters during different working cycles. Measurements can be made continuously, on scheduled plans, during working downtimes or change of parts. The adoption of LPMs to monitor laser processes consequently provides a substantial increase of efficiency in the system and reduction of costs. SIMPLE AND POWERFUL The LPM bears the function of fixing an operative range acceptable to maintain functionality and quality on the process and then get alarm signals, that avoid major damages and time losses, if that acceptable band has been overtaken. These limits can be either set directly on the electronics or via the LPM’s software (LPM-SOFT). There are various ports for external communication, all included as standard features: Analog Outputs (Opto-Isolated 0-10V or 4-20mA , Digital Output (Opto-Isolated RS232 (RS 485 Mod-BUS Protocol-optional)) and a Process GO/NO GO Relay (220V, 10A). The main page of LPM-SOFT, of very practical use when tracking laser stability or during beam path alignments, displays both the safe working band and shows a warning red led. The LPM can work with all types of detectors including LaserPoint’s FIT-H power probes (they provide complete information in 6 seconds and read up to 6KW without water cooling). An LPM set-up is made by the electronics, a detector and the application software. Detectors associated to the LPM can be installed at any convenient location on the working plane or along the laser beam path, e.g. after a beam sampling optics.

LPM ELECTRONICS. The electronic board can be easily plugged inside any laser or machine cabinet on standard MR9 DIN rails and allows operation on 2 different modes, user’s selectable: ■Remote operation The LPM dialogues and gets commands from the machine control unit through its serial interface RS232 (RS485 on request). A full featured application SW (LPM-Soft) reads values, allows to set alarms for process monitoring or system malfunctioning, to carry out statistical evaluations on running measurements, to save and download data. ■Local operation It is the most simple way to use the LPM which will only generate alarms, for example by switching-on an alarm lamp. The LPM monitors the laser power/energy and checks whether their values remain within two acceptable (Min/Max) threshold limits, preset on the electronics itself. Those two values are stored within the LPM memory by a self learning algorithm after a simple exposure of the detector to the laser beam, running at the Min and Max levels . If power/energy are out of limits, the alarm is generated, e.g. by means of a relay connected to the laser PLC. Additional alarm LEDs, located on the board itself will turn their colours. Two additional analog outputs ( 0-10V and 4-20mA ) can be used to know the absolute value of power or energy or tracking laser stability by means of multimeters or plotters. DETECTORS FOR THE LPM The LPM can work with all kind of detector heads manufactured by LaserPoint: this adds flexibility and expands the range of applications to the system. ■Power Meter Mode: This mode allows a continuous measurement of laser power. It helps during machine settings, can be used to monitor long term laser stability, optics alignment, etc. Operating range is from very low powers up to 6KW, CW. ■Laser Probe Mode: the OEM laser probes (Fit-H Series) allow power monitoring done on short laser exposures. This mode of operation is carried out by special detector heads and a patented method that allows automatic measures made in just 4-6 seconds, depending on the head model. The range of operation is from 50W f.s. to 6KW f.s. Together with lower costs for the detectors, another major advantage is that there is no need for water cooling even at multi-kW powers. Measurements with Fit-H heads can be programmed between working cycles for a quick check of the constancy of laser power, to verify new set parameters (e.g. to verify that power is really what is needed by the workpiece ), after components have been changed or realigned, etc. In practice, whenever long running measurements are not necessary. ■Energy Meter Mode: This mode is used to measure single shot pulses. Typical application is the monitoring of marking or micro welding machines. Available ranges go up to 600J (long pulses).

LPM-SOFT: APPLICATION SOFTWARE The LPM-Soft is a powerful application software provided as standard with each LPM . The LPM can plot evolution graphs of time behaviour of laser power, display energy or FIT-H readings in the form of histograms, show the absolute values of power and energy, provide all relevant statistical information and allow the storage of data to files, as a text format usable for Excel or other programs. The LPM also allows the management of laser processes and laser tuning. ■ Display Functions ■ Head Model: shows the head model in use ■ Lambda: shows detector’s calibration wavelength ■ SN: shows the head serial number ■ Actual Time: shows present day and time ■ POWER (W/mW); ENERGY(mJ/J): shows measured power or energy values. ■ User Calibration Factor: this number will multiply the actual measured value by a selectable factor to reach a desired value. ■ Head Temperature (°C): shows the temperature on heads provided with temp. sensor ■ZERO: accomplishes an automatic Zeroing ■ TUNING: Enables the Tuning Function ■SAVE: Enables the automatic function to save measurements on a file ■ PRINT: prints the displayed window ■ QUIT: leaves the program ■Power Measurement Scales ■ Graph Power Max/Min (W) sets the extention of Y axis on power plot. ■ Graph Time: sets the duration of Time axis (X) for the power plot; available time scales are 60(sec), 2(min), 5(min), 30(min), 1(hour), 12(hours). ■ Laser Process Management An important feature offered by the LPM Software is the possibility to monitor the ongoing laser process and get an alarm feedback in case the acceptable range for power/energy levels have exceeded the pre-set limits. This feature extends the LPM applicability to rigorous control and monitoring of industrial applications. ■ Setting Process Parameters ■ MAX/Min Power Levels: set process limits that remain visible on the screen as red lines, defining the acceptable working range. ■ Alarms: the rectangular Led, when green, shows that measured value is within the acceptable range . When red, it shows that measurement is no longer within the acceptable preset working range and that an intervention by the operator may be necessary

Mod. Fit-6000H. Max Power: 6KW CW Size: 100mm (L)x 100mm (Dia) This type of detector allows laser power measurements in 6sec. and has no need for water cooling. Its most standard use is to associate it to the LPM to make once-in-a-while controls of laser power and predict incoming failures, e.g. of optical components. This is fast and conveniently done by comparing the power value, read on the laser controller, to what the LPM tells, having the detector placed below the focusing head. A too high difference may indicate that damages already occurred; a small difference, higher than natural losses, indicates an incoming degradation thus showing that optics must be cleaned, replaced etc.


■ Statistical Functions A full set of Statistical functions is provided by the LPM-Soft. The Duration of acquisition interval can be selected to be as long as 24 hours. Once data have been gathered, SAVE enables an automatic saving on file for data recording or future data tracking . Statistical Functions include: ■ Max/Min (W,J): the max/min power/energy values measured during the last acquisition interval ■ Avg (W,J): the average values of power/energy measured during the last acquisition interval ■ PTP (%): the Peak-to-Peak stability ■ STD (W): the Standard Deviation on measured data ■ RMS (%): the RMS stability ■ Tuning A fast and highly visible Tuning Bar is available for tweaking or alignments. It displays variations of measured power on a double colour bar (green and red). The Power Variation (%) box shows how much power was gained or lost from an initial reference level. To remind the operator what has been the highest reached value, the Power Max(W) box stores that value . Evolution of laser tuning can also be comfortably followed on the screen. ■ Warning Message All times measurement heads undergo to power levels above their full scale, an OVERFLOW alarm is displayed. The same way, whenever the temperature of a detector head is above its safety working limit, a COOL alarm message is displayed.

It can be delivered already boxed or for installation inside industrial cabinets on standard MR9DIN rails. Detectors can be placed up to 5m away from electronics, e.g. on spots where they do not interfere with manufacturing.

Applications of Laser Process Monitor (LPM) ■ Operation in Remote Mode The LPM detector head may be located as permanent unit in a non used corner within the process area or any other spot, within the laser system or machine, where monitoring is necessary. It is important that the beam be large enough not to damage the detector absorbers (the detector can be fixed a just underneath the focal plane so that it will be sheltered from moving carriages and is of no disturb to the process). The acquisition and processing board is connected to MR9 DIN slim rails, available on any industrial cabinet or rack. It interfaces with the laser PLC or an external PC with a protocol Mod-BUS through the serial interface RS232. A powerful, yet friendly, software interface allows to read the power or energy values delivered at the process area, set the alarms, carry out statistical evaluations, etc in the Power, Energy, Probe configurations. Whenever preset alarm thresholds are overtaken, visual messages are displayed on the screen or alarm signals can be custom used e.g. to stop the process. During the phase of machine validations, beam delivery alignments or whenever measurements of long term stability are made, the software of LaserPoint LPM can show on a large graphical screen, the time evolution of power in measurement sessions which may last many hours. Should a high resolution be needed to look at events occurred in a short period (e.g. a sudden power drop), a zoom function can be used to observe on a tighter time scale. The Statistical Functions screen is an even more powerful tool during long term monitoring since it provides all relevant data like Min and Max values reached during the measurement period, the Average value of measurement, the Standard Deviation and the Root Mean Square values. Data can then be saved, with day and hour of measurement, to be used as a documentation for final reports or for the customer.

■ Operation in Local Mode The LPM detector head can be placed in a remote area close to the process or in any other spot, within the laser system or machine, where monitoring may be necessary. The acquisition and processing board is connected to MR9 DIN slim rails, within the control unit or any other place where it may be useful. LPM can monitor the laser power (or energy) and checks whether it is within two preset threshold values. Measured values can be read via a 0-10V/4-20mA analogue output and trigger alarms via a potential free contact. Those signals can be used to switch alarm lamps or acoustic signals. Alarm thresholds are set by a self learning algorithm while exposing the sensor to the laser beam tuned at the MIN-MAX power or energy alarm levels. Operating in Local Mode is particularly useful in case of retrofitting the LPM set-up on older machines, where the integration of its SW is not possible.

■ Operation in the Probe Mode ( periodic power check)Measurements runs can be planned to accomplish short controls of beam power during working cycles, after laser parameter resetting, optics realignment, etc. The use of special FIT (Fast Integrating Thermopile) heads that do not require any water cooling, even a many kW, is of great help in many industrial environments where having water at the application area is a problem. The acquisition and processing board is connected to MR9 DIN slim rails and housed in industrial cabinet or rack. Data can be analysed by the specific SW for the Probe Mode or, should immediate warnings be needed, visible/ acoustic alarms can be triggered.

Prediction of incoming failures ,e.g. at optical components, can be easily done by cross checking the power/energy delivered by the laser source and what is effectively delivered to the work piece. A too high difference between the two values may indicate that damages already occurred.

■ Beam Delivery System: Alignment & Stability The complete beam path can be aligned and verification that the max yield at the work piece has been reached can be done with LPM working in the power/energy mode. Successive measurements of system stability can be done and visualized with the most relevant statistical information on the beam behaviour.

■ Monitoring of Marking, Micro-welding, and Micro-Machining Systems Monitoring of energy or power as they are delivered after the focusing lens, providing a fast and direct control of the correct values for the process, of the optical system or optical fiber integrity can be done with LPM simply displacing the optics or the translation stages.

■ Control of Stability of Process Parameters Setting of working cycles with measurement of the power really delivered to the work piece can be done with LPM , operating in power mode. It can be done as a simulation before working, to verify the correctness of process parameters, or in certain phases decided by the operator, e.g. during the dead times between welds, to check that preset parameters did not change for reasons like optics damage, dirt, etc.

The 3B: Laser Power + Beam Diameter & Position Finally a cost effective, simple to use, precise industrial tool for measuring 3 beam parameters, all relevant in laser processing: the laser beam power, its diameter and its variations, the beam position and its changes. The value of laser power is provided by heads that come with NIST/PTB calibration; diameter and displacement are given with 100µm resolution. All from the same instrument. This instrument is also totally safe and environment friendly since there is absolutely no emission of toxic fumes, as it happens when burning plexi sheets on similar applications. What achieves all this is the 3B , another goal from LaserPoint technological developments. The 3B is a monitoring system that measures, displays, stores and logs data of the above fundamental parameters of a laser beam. It’s integration within machine control systems, offers new and unique diagnostic possibilities to system integrators, end user and service engineers.

Examples of 3B applications are: ■ Alignment of machine’s complete beam lines, from laser source to focussing lens. ■ Check of displacement of focus height over the entire working area (e.g. in flat bed laser cutting or welding applications) by mapping, with off-focus diameter measurements, the area of interest. ■ Monitoring of welding processes by linking diameter variations to the corresponding shifts of focal positions. ■ Map ping of laser beam diameters for applications using adaptive optics. 3B: THE SYSTEM The 3B is a semi-automatic system composed by the following sub-assemblies:

• the 3B Detector head which faces the laser beam and absorbsthe complete power up to 6KW. A major advantage of spanning to the maximum of laser power, is monitoring at the same beam conditions used in the working application.

• the 3B Electronics box hosting microprocessor controlled electronics units with high reading accuracy and resolution for data collection, analysis and display and data logging. The data logger has a large memory and a fast offload speed .

• SW packages: one for data measurement and visualization with PC and the 3B Data Logger Software to save/access memorized data .

The 3B can work either associated to a PC or as a Stand Alone unit. Operation with a PC allows Alignment operations, Live and Long Term Monitoring, and Quick Measure of Laser Parameters; this latter operation

can also be made when working Stand Alone , in which case an external PC is only used to download stored data. Three working modes are switch selectable from the 3B electronics housing: • StandAlone: the 3B measures and internally stores data without communicating with a PC • PC« 3B: In this operating mode the 3B is controlled by a PC, via the supplied 3BSoft. • DL« PC: in this mode the Data-Logger is in communication with a PC, via an RS232 serial port, to download

measured data gathered and stored in the Stand Alone mode. The 3B readout and data logger electronics are embedded in robust, IP65 rated cases.


■ Initial References: Set-Up and Alignment To maintain, over time, a constant quality for the running process it is necessary to set the acceptable tolerance for each of 3B’s working parameters (e.g. set the Min and Max power ). Alarms signals will be generated each time the defined limits are overtaken, whichever operational mode of the 3B has been selected. The handling of these signals will be managed by, e.g., the machine’s PLC to switch-on alarms or stop

the process. Values of alarm settings will be automatically saved and stored within the 3B internal memory . At the initial stage, prior to any measurement, the 3B head has to be perfectly aligned and positioned to be centred onto the system optical axis.

Alignment and fixing alignment parameters are very preliminary operations, necessary to have information which will be used as references for next measurements. Any further occurring change will be then referred to those reference values. With a perfectly aligned beam, X and Y will be at 0; nevertheless, if the application can accept some tolerances, X or Y can be slightly shifted, e.g., by 0.1mm. These values will be the references and any successive variation will be thus referred to 0 (or 0.1). For alignment purposes, the 3B detector has to be located in a fixed position and its electronics connected to a PC; the laser beam is moved looking for the sensor centre, until the screen shows the X and Y values = 0; alternatively, a carefully pre-aligned (e.g. mechanically) 3B head can be finely moved facing the laser beam until X and Y go to 0. After the set-up procedure and the system alignment , the 3B can be used either for Live Monitoring, typical for continuous measurements that run over long periods, or for Quick Measures that last a few seconds . 3B OPERATIONAL MODES ■ The Stand Alone Operation The Stand Alone Operation is provided for periodic and quick overlooks of laser parameters in environments where PCs

are not directly available on the process site. A PC is only needed for the initial alignment and set-up. The Stand Alone Operation is used to verify that beam behaviour remains constant , at least within pre-fixed limits, over a period which can be days or weeks. Each of these periodic checks only lasts some seconds after which beam data are stored within an internal memory to be, anytime later, downloaded to a spreadsheet (e.g. into an Exel file) by means of the data-logger . The max number of acquisitions is 1552, which permits, for example, to monitor laser parameters every ½ hour over a period of 1 month before the need of downloading! This feature provides a tracking of working parameters unavailable up to now.

There is no screen visualization of data but, for the safety of the process, should Power, Diameter or Displacement exceed their pre-set acceptable working range, alarms will be however generated. In Stand Alone operation when laser power is above a starting threshold, the LED corresponding to MEASURE blinks and, at the same time, the “ Measurement in Progress” contact will close on the AUX I/O connector. As the measurement is over, acquired data will be stored within the 3B electronics and the contact will open. The 3B internal memory will be continuously filled to its limit of 1552 acquisitions

after which a download of data to PC is necessary Should any of laser parameters be out of the pre-set band, the corresponding LED will light and the corresponding contact will be closed. The DB25 Aux I/O connector is used for the trigger input and connections with external alarm relays to start alarm lamps, stop the process , etc.

. ■ PC Operation and the 3B Soft (PC ⇔ 3B) When the 3B is connected to a PC (PC «3B), the 3B Software screen will display a multi-function page that bears several, easy to use, operational boxes and displays to give access to the set-up page, the alignment function, live or periodic monitoring.


■ Long Term, Live Monitoring The main page shows, in real time, measured values and whether modifications of the laser beam are occurring .

■ Power: the beam power value is displayed in Watts. ■ Diameter: shows the beam diameter with 100µm resolution. ■ X Centre and Y Centre: are the calculated centroid position along the X and Y axis. Any displacement is shown in real time with 100µm resolution. ■ Centroid & Diameter: two black circles define the Min and Max acceptable beam diameter which have been preset in the Set-Up page . When the laser is switched on, a third ring (blue) simulates the laser beam with its average diameter and position. If the blue ring location remains within the limit rings, its centroid (red dot) shows how far the beam is from the alignment position (e.g. X=0 and Y=0). ■ Behaviour of Power, Diameter and X-Y Pos. with Time:

3 boxes display the evolution of laser power, beam diameter and beam positions vs time over a period from 1 min up to 12 h. Values are continuously updated. The 2 horizontal lines within the boxes show the alarm limits previously selected; the graph and the exceeded limit line will display an alarm message by changing colour. ■ Print: prints a screenshot of the complete window. This print can be used as a calibration/alignment document available for the customer or for report files of service engineers . During operation some error messages may be displayed:

■ Overload: the actual laser power is above the maximum limit permitted by the head.

■ Diameter is Not Available (N/A): the actual value of the beam diameter is larger or smaller than limits acceptable by the head. (e.g. when laser warms-up). ■ Align: the actual position of laser beam exceeds the limits set by user.

■ Periodic , Quick Measure of Laser Parameters Whenever long term measurements are not necessary, the 3B can alternatively be used to make periodic controls or monitoring (every few hours, per day or week depending on the application necessity) to verify that the laser process is still done at the originally set parameters. Similarly to Stand-Alone operation, but with information shown on a PC screen, the Measure key on the main page opens a page for this type of quick measurements. Each measure only lasts a few seconds and takes a picture of the beam situation in that moment. This other way of using the 3B is also straightforward: shortly after the laser has hit the detector, measurements automatically start and the period to go appears on a countdown box ( “Run X”, down to “Run 0”, where X stays for the remaining number of seconds ). Measured data will be displayed as histograms in order to provide an immediate view of stability or evolution for each parameter . The max number of measurements displayable on each frame is 30, after which histograms will scroll . Again, each frame contains the alarm thresholds (shown as continuous horizontal lines): when these values are overtaken, the lateral LED corresponding to the parameter above the limit will light on, while a mark will be added to the corresponding histogram. Parameter scales can be expanded or reduced by acting on 2 lateral sliding windows. A “Print” key is available to print a screenshot of this window. In any case all data collected during the measurement session are automatically stored in a file and can be read with a text editor program or imported into a spreadsheet, e.g.Excel.


■ Datalogging (DL ⇔ PC) Communication between data logger and the 3B electronics is enabled by the front panel switch (DL « PC) and through the serial communication port RS232. For data downloading, a specific, exhaustive Software is included in the package. Once the EXE program has been launched, some initial instructions like the serial port selection (COM X) and Connect are provided on the screen. Initial configuration also includes an EraseEeprom and Set Time/Date; once they have been set, a simple click on the Send Command key will store data. Specific requests can be asked the 3B: for example Read How Many Bytes Are In EEPROM, in case it is necessary to verify if the memory is empty and avoid to mix up new data with others from a previous measurement session. The Erase EEPROM function from the Command box and Send Command will clear the memory, if necessary.

Other commands are also available: ■ Stop Time: brings the clock in stand-by mode, blocking an internal clock. ■ Read Current Status: gives information on the Datalogger status, like: - Command Error - Ext. Memory Overflow - PIC EEPROM error - Ext Memory is empty - Status Ok Controlling the status reports

about wrong or illegal commands, informs if the external memory is full or whether errors have occurred within the microprocessor non-volatile memory; another error message tells when configuration or memorized data are read but memory is void. Status OK is for normal operation . When data are downloaded they will be located on a new page, containing various fields like Frame No ( frame number), Time/Date (day and hour of acquisition), Power and its Status, XPosition and its Status, Y Position and its status Status, Beam Diameter and its Status). A status bar shows the % of filling of the table and unless the bar does not reach 100%, data will not be displayed. The Save Data function permits to save data in a text file ( which can be read by most of electronic sheets).


3B: DETECTOR HEADS The 3B can be used with all high power industrial lasers (CO2, Fiber, Nd-Yags, Diodes) on power ranges from 600W to 6KW. Depending on the application, the detector can be mounted at various intersections of the beam path (e.g. at the mirrors location), with specific adapters or in a fixed position at the end of the optical chain. Detectors can withstand the full laser powers. This is a big advantage since beams often change their properties (mode, position, diameter) when the laser is operated at low or high powers, in particular if they are gas lasers (C02). Readings of laser power are extremely accurate and a NIST/PTB traceable calibration certificate for the head is given to prove it. In the case of space or weight restrictions, e.g. if the head has to be mounted on board a machine, a smaller 600W head can be used, by making the laser work at a low duty cycle (e.g. at a duty cycle of 10% if the head has to be used on a 6KW laser )-

Advantages of LaserPoint OEM Laser Measurement Products

■ Reliable and Versatile Measurements ToolsOEM sensors discs manufactured by LaserPoint arehigh sensitivity, low impedance thermopiles. Highsensitivity is important to maximize the signal-to-noiseratio when working at low powers . Compared to other types of sensors which might beused in equivalent applications, thermopile detectorscan be applied directly onto the beam, even at highpowers. LaserPoint sensors are made with resistant materialsand coatings that extend their applicability from UV toFar Infrared and to concentrated beams, withoutdamaging even at extreme power densities. LaserPoint provides thermopiles which exhibit a highdegree of linearity over their entire working range andhave large areas that sample the whole laser beam. Thermopile sensors are almost insensitive to theposition and the size of beam when it strikes on theiractive areas. Alignment is never critical and installationtime in OEM applications is fast. Everything has been designed to provide accurate andreliable measurements of lasers like CO2, Excimers,Laser Diodes, Nd-Yag from 3W to 200W atcompetitive pricing . ■ Compact Design Off-the-shelf sizes of sensor discs range from15x15x3mm to Dia 90x6mm, with active areas up to40mm. ■ Calibration All OEM sensors undergo to a series in houseinspections and controls, which include individual testsof sensitivity and impedance.

The PC-Link a smart head to USB interface, converts any PC or laptop into a power or energy meter. The PC-Link is supplied with a user-friendly communication software package for single channel or dual channel operations. When 2 heads are connected to the PC via two hardware boxes, the PC-2-Link SW provides data or compares signals from both heads. To work with PC-Links is very easy: connect to the USB ports of a PC and install the software. No other operation and external power source are needed. This sophisticated monitor is plug and play with all LaserPoint heads, it is very compact and has low weight: these features make of this monitor an ideal partner for service applications or OEM use offering the convenience, flexibility and value of computer-based operations. The PC-Link is infact the candidate for use in laser machines, in particular when associated to LaserPoint’s FIT-H (Fast Integrative Thermopile Heads) family of OEM detectors.

Applications of OEM Sensors & Heads A-THERMAL SENSOR DISC AND HEADS ■ Laser source monitoring This is by far the most popular application of OEM heads. They are placed behind laser rear mirrors and catch the <1-2% radiation leaks exiting from these mirrors; that amount is strictly proportional to the total emitted power so its measurement results to be very reliable. Given the small leakage fraction, multi-kilowatts sources can be continuously monitored by low power sensors. Though the final validation of a laser source, including the calibration of its internal power sensor, is made by a power meter, yet OEM sensors provide successive field monitoring, are used for later alignment purposes and setting of process parameters.

■ Fiber monitoring Monitoring the integrity of fibers delivering Nd-Yag, Diode laser, medical lasers beams, either at high powers or low powers, can be done by picking up the residual beam portion (< 0.5-2%) non reflected by the total 90º mirror in the focusing heads.

■ On-line monitoring On-line monitoring can be easily achieved by exploiting the leaks of existing optical elements or keeping dedicated components (like beam splitters, filters, diffractive optics, etc) into the beam path.

■ Beam dump In some medical applications the laser must be kept running at its working power or energy even when it is not in use for treatment. The necessary power/energy must be immediately available for the short periods of application and there must be no delays (e.g. warm-up times). OEM heads are used as beam dumps for the non-operating periods and an extractable mirror releases the beam for the application.

■ Sampling at measuring port Several medical machines bear a port for time-to-time measurement of laser power or energy. In Countries like the US it is a precise requirement from FDA to have a monitor for each laser on-board the machine. OEM heads are plugged into the ports to read the power or energy available for treatment exiting, e.g. from optical fibers. Moreover, since optical fibers or fiber tips crack very easily, frequent checks are a wise solution.

B-OEM LASER PROBES (FIT-H SERIES) ■ Operation in the Probe Mode (power check) Measurements runs can be planned to accomplish short controls of beam power during working cycles, after laser parameter resetting, optics realignment, etc. The use of special FIT (Fast Integrating Thermopile) heads, which do not require any water cooling even at several KWs, is of great help in many industrial environments where having water at the application area is a problem. The OEM laser probes are perfect for use with the LPM electronics whose acquisition and processing board can be plugged on any standard DIN rail and housed in industrial cabinet or rack. Data can be analysed by the specific SW for the Probe Mode or, should immediate any immediate warnings be needed, visible/ acoustic alarms can be triggered. ■ Periodic controls in manufacturing Periodic monitoring and control of power in laser cutting or welding machines. The LPM software allows the setting of alarm thresholds for a GO/NO GO of manufacturing process

■ Systematic monitoring of process parameters Periodical monitoring and control of constancy of power level in laser robot applications for total repeatability of process The LPM allows the setting of alarm thresholds for a GO/NO GO of manufacturing process

■ Predictive Maintenance Prediction of incoming failures ,e.g. at optical components, can be easily done by cross checking the power/energy delivered by the laser source and what is effectively delivered to the work piece. A too high difference between the two values may indicate that damages already occurred.

■ Monitoring of Marking, Micro-welding, and Micro-Machining Systems Monitoring of energy or power as they are delivered after the focusing lens, providing a fast and direct control of the correct values for the process, of the optical system or optical fiber integrity can be done with LPM by simply displacing the optics or the translation stages.

Laser Power Probes Fit and Cronos

Many applications do not require the tight specifications of power meters. For others it is simply sufficient to make quick checks and there is no necessity to measure over an extended period of time; while it is sufficient to have readings in a snapshot just to monitor if power is ok. Sometimes water is not available on the machine. Many times it is a bare matter of limited budget. That’s the world for a different class of instruments known as laser probes or power probes. Those instruments are stand alone units made of a thermal probe connected to an electronics and its display. In general, existing instruments of this type are thermometers that measure a temperature difference in a fixed time and have a simple dial or a digital display. They have a number of major drawbacks, like their dependence on measurement time, which in most of cases has to be evaluated by the operator, their poor repeatability or accuracy, the fact that after each measurement they need to be cooled, etc. LaserPoint has introduced a real breakthrough in the field with two series of fully automatic laser power probes that calculate laser power by a microprocessor based measurement of temperature dynamics. Their measurement and acquisition technique self-determines the time needed to carry out a measurement: data acquisition is triggered and stopped by detecting set heat parameters thresholds. This technique is totally free from induced errors due to measurements of exposure times and may allow multiple measurements without the need of forcing cooling to the absorber. Both Fit and CRONOS feature a large multifunction LCD that simultaneously indicates the measured power, the wavelength of calibration (CO2, Nd-YAG) and low-battery. Furthermore a moving bar shows the actual absorber temperature; this informs the operator whether he can still perform more measurements before the absorber reaches its maximum allowable temperature and needs to be cooled. Additionally, the probe status is displayed by a two colour LED: probe is ready (steady green), measurement is in progress (flashing green), measurement is over (steady red) or cooling is needed (flashing red). Fit and CRONOS are both operated by a single button. They store the last measurement in memory and shut automatically off after 5 minutes of non operation. Two common AA batteries allow a minimum of 5000 measurements. Fit and CRONOS have been ergonomically designed in all their details like the LCD display and the balance of weights, to provide a comfortable and safe operation. The absorbers feature low reflections and high damage thresholds; in particular the hi-power, multi kilowatt CRONOS have a concave conical shape to avoid dangerous back-reflections toward the operator. Recalibrations can be made user. Fit, with its low profile sensor head connected to the display body by 1m extensible cord, allows remote testing even in tiny spaces.

Applications of LaserProbes Laser Probes can be used in a variety of applications. Up to now they have been the standard measurement tool for service engineers who could rely on their portability, ease of use and quick measurement time. The new generation of probes manufactured by LaserPoint extend their range of applications and makes them available to laser technicians of any level, to any industrial job shop for internal controls, for periodical controls of medical equipment. This is due to the number of advantages that both FIT and Cronos probes offer, when compared to old generation equipment. For example a high degree of measurement repeatability is necessary to verify whether a source is stable or is drifting or whether the best available power has been reached after an alignment session . On standard probes, who have an error bar of 10% (+/-5%), such an uncertainty can be misleading. Fit and Cronos, with their possibility to repeat several measurements beginning a few seconds after the previous one and without stopping minutes for cooling and rinsing, offer a double advantage: save time and work with the same laser conditions. Automatic measurements mean that there is no need to measure the exposure time and that, for this, no errors are introduced. The 4 or 8 seconds are decided by the internal clock of FIT and Cronos which start and stop measurement above a triggering level. The operator can keep the probe a longer time under the laser or even insert it in a running beam: no measurement errors are made. Readings can be done by a single person rather than the usual two operators, one at the control unit to open/close the shutter and the other one on the machine to make the measurement. The possibility to store and recall the last measurement value helps in many industrial works, where hurry and multi-task activities may distract laser operators. Accuracy and a high degree of repeatability of measurements are what is needed by several medical applications to know the exact power delivered to a patient. The Fit series has performances equal to power meters so that FIT probes can be a powerful substitute whether there no other needs, like long term monitoring. At a fraction of power meters cost. ■ Laser Alignment Verification if maximum power has been reached after tweaking can be done in 8 sec with Cronos or 4 sec with FIT. This measurement is very useful as a cross-check with laser internal power monitor.

■ Laser Power Monitoring Periodical verification of real laser output can be done with laser probes, in particular if there are doubts on effective delivered power. A practical case is when the laser internal monitor displays a value, but the application is not running properly.

Control Unit


■ Monitoring of complete beam delivery systems at the workplace A monitoring of the complete beam line, down to the workplace, can explain why cutting, welding, etc do not perform well. Cronos and Fit can easily show discrepancies with the internal laser monitor, indicate that there may be damaged components on the beam line or power losses due to misalignments.

■ Verification of Damaged or Dirty Components Locating damaged optical components can be done easily by making a reading before and a reading after the component itself. Optical components in good shape never lose more than a very few percent of laser power. Major losses can be ascribed to damages or dirt; in any case changing the optics or clean it will save future troubles and costs. FIT and Cronos probes are ideally suited for this kind of verification since their reliable measurements permit to trust the readings and the possibility to make another measurement, a few seconds after the first one, is practically independent from laser fluctuations.

■ Fast monitoring of marking and micromachining systems Low and mid power lasers can be efficiently monitored by the FIT series. The 1% repeatability and high resolution (10mw on the 50W model) of those probes, make their measurements the reliable references for setting application parameters or for periodical verification.

■ Fast monitoring of medical lasers Periodical monitoring of CW medical lasers (CO2, Yag, Argon etc) can be quickly done (4 sec) with highly reliable and precise FIT probes. Verification of losses within articulated arms, breakings of fiber tips, damages on focusing optics or handles are immediately detectable thanks to the high level of repeatability and high resolution of those probes.

Fit-IPL:Energy Meter for Intense Pulsed Light FFiitt--IIPPLL--RR is a fully automatic, hand-held energy and power meter designed for IPL (Intense Pulsed Light) applications. FFiitt--IIPPLL--RR works on a microprocessor based patent pending measurement technique of temperature dynamics through a thermopile sensor. Measurement and data acquisition are fully automatic, making this technique virtually free from operator induced errors.

FFiitt--IIPPLL--RR is extremely friendly in use and features a large rectangular exposure area (60x18mm) to match with all handpieces. The broadband detector works in the range from 400 to 1400 nm, which is the range of interest for the majority of applications (photoepilation, skin rejuvenation,

treatments of acne, vascular and pigmented lesions, psoriasis). The absorber coating of FFiitt--IIPPLL--RR remains fully responsive also when filters are used to reduce the lamp spectral bandwidth. This absorber is very robust, as it has been designed to face the extreme fluences (up to 90J/cm2) of professional systems (medical and clinic) where the highest pulse energies are involved. But it is also very flexible since it can operate with semi-professional systems (beauty salons) and consumer-oriented systems (2 to 10J/cm2). FFiitt--IIPPLL--RR has a window for gel or water coupled handpieces but can also measure air coupled IPLs. The unit bears a multifunction LCD that simultaneously indicates the flash-lamp energy (or power) delivered by the handpiece; it also shows the mode of operation [Sin for single shot (energy) or rEP for repetitive

(power)], probe model and warning for low-battery. A bargraph shows the sensor temperature to inform the operator whether he can still perform more measurements before the sensor reaches its maximum allowable temperature. Additionally, the probe status is displayed by a two colour LED indicating if the instrument is ready for measurement, if the reading is in progress or over and if cooling is needed.

An important feature of this instrument is the possibility, given to users, to match to a custom reference or make in house re-calibrations by means of a lateral micro-switch usable to modify the sensitivity.

FFiitt--IIPPLL--RR is operated by a single button; it shuts automatically off after 5 minutes of non operation and always stores its last measurement in memory. Two common AA batteries allow a minimum of 4000 measurements.

Fit-IPL-R can measure both flash-lamps single shot energies up to 350 Joules and average powers, when in burst mode operation, up to 100 W. Fit-IPL-R innovative measurement concept reduces the time of measurement and display to 10 sec. with excellent repeatability (±1%), accuracy (±3%) and high resolution (10 mW and 100mJ) associated with a wide dynamic range of measurement (down to 1% of f.s.).

Customer Support LaserPoint is proud to support his Customers to the highest level. Should you need information which you do not find on our catalogue or need to discuss technical and commercial aspects, our Engineers and Sales staff will help you simply by calling or writing. ■New OEM Projects If you are designing a new laser source, system or machine and need a custom detector or monitoring set-up, just fill and submit by fax or email your requirements providing laser data, system specs and application; LaserPoint will be back to you with a proposal. If an NDA (Non Disclosure Agreement) is required for your project security, we can sign it as we normally do with many of our Customers. ■Post- Sale Assistance -Should an instrument be serviced in or after the warranty period, you are kindly requested to ask for an RMA number. Please fill the RMA form indicating faults and encountered problems. The RMA number will facilitate tracking the returning instrument and your information help our Engineers in their diagnose. -Dou you need additional technical support on the instrument or on how to use it? Just contact LaserPoint by phone, fax or e-mail and you will get an appropriate answer. -If you need to add an additional head or use your existing system within a different application, ask for a free consultancy to LaserPoint. A simple phone call or an e-mail may address you to a more suitable approach or even save your instrument coating. ■Recalibration It is a good rule to recalibrate instruments once a year and to do this it is necessary to ship back the units to LaserPoint. You also need to get an RMA number, which is simply obtainable by filling the associated form. Recalibration is done within a few working days from receipt, but maybe during this period you still need a calibrated instrument in your lab : ask LaserPoint or one of our Distributors for a spare unit, just to fill the gap. ■Manuals Have you lost the instruction manual or some descriptions are not clear enough? Contact Laserpoint directly or email to [email protected] for any additional support might be necessary.

Returns for Calibrations and Repair Prior to shipment: 1-Ask directly to LaserPoint or one of his Distributors for the RMA(Return Material Authorization) Number. This will be issued andquotation will follow immediately after the receipt of material inLaserPoint . 2-Report: -Model Number -Serial Number -Purchase Order Number and date -Shortly describe defects (if any) 3-Ship to: LASERPOINT s.r.l. -Via Burona,51 –Vimodrone (Milano) –I20090 Italy or to one of our Distributors Return time Time to calibrate instruments normally occurs within 5 working days after receipt. A faster service is available at an additional charge (please ask).

A Final Safety Rule Never exceed the power density limits specified for your sensor. To preserve both accuracy and life of detectors, it is necessary to operate within the power or energy densities specified for each model. Exceeding those limits physically wears coatings and materials, modifies spectral responses and thus measurements.
